Getting fed up :-( cycle day 61!

On cycle day 61 and starting to feel really fed up now! Numerous BFN's so definitely not pregnant and only one AF since coming of my birth control pill in October last year. Went to my family planning nurse and she said they won't do anything until we've been trying for a year, I'm finding it difficulty to stay positive I no people have been TTC for a lot longer but is there anything I can do to help my AF be more regular? I feel useless!!
